Large-x resummation of off-diagonal deep-inelastic parton scattering from d-dimensional refactorization [PDF]

Journal of High Energy Physics, 2020
The off-diagonal parton-scattering channels g + γ* and q + ϕ* in deep-inelastic scattering are power-suppressed near threshold x → 1. We address the next-to-leading power (NLP) resummation of large double logarithms of 1 − x to all orders in the strong ...

Asymmetric jet clustering in deep-inelastic scattering [PDF]

Physical Review D, 2020
We propose a new jet algorithm for deep-inelastic scattering (DIS) that accounts for the forward-backward asymmetry in the Breit frame. The Centauro algorithm is longitudinally invariant and can cluster jets with Born kinematics, which enables novel ...

Lepton-jet correlation in deep inelastic scattering [PDF]

Physical Review D, 2020
We study the lepton-jet correlation in deep inelastic scattering. We perform one-loop calculations for the spin averaged and transverse spin dependent differential cross sections depending on the total transverse momentum of the final state lepton and ...

Non-perturbative structure of semi-inclusive deep-inelastic and Drell-Yan scattering at small transverse momentum [PDF]

Journal of High Energy Physics, 2019
We consider semi-inclusive deep inelastic scattering (SIDIS) and Drell-Yan events within transverse momentum dependent (TMD) factorization. Based on the simultaneous fit of multiple data points, we extract the unpolarized TMD distributions and the non ...

Deep inelastic scattering on the quark-gluon plasma

Journal of High Energy Physics, 2021
We provide an interpretation of the structure functions of a thermal medium such as the quark-gluon plasma in terms of the scattering of an incoming electron on the medium via the exchange of a spacelike photon.

Semi-inclusive deep inelastic scattering in Wandzura-Wilczek-type approximation [PDF]

EPJ Web of Conferences, 2019
We present the complete cross-section for the production of unpolarized hadrons in semi-inclusive deep-inelastic scattering up to power-suppressed O(1/Q2) terms in the Wandzura–Wilczek-type approximation which consists in systematically assuming that q ...

Extraction of partonic transverse momentum distributions from semi-inclusive deep-inelastic scattering, Drell-Yan and Z-boson production [PDF]

Journal of High Energy Physics, 2017
We present an extraction of unpolarized partonic transverse momentum distributions (TMDs) from a simultaneous fit of available data measured in semi-inclusive deep-inelastic scattering, Drell-Yan and Z boson production.

Beam-helicity asymmetries for single-hadron production in semi-inclusive deep-inelastic scattering from unpolarized hydrogen and deuterium targets

Physics Letters B, 2019
A measurement of beam-helicity asymmetries for single-hadron production in deep-inelastic scattering is presented. Data from the scattering of 27.6 GeV electrons and positrons off gaseous hydrogen and deuterium targets were collected by the HERMES ...

Diffractive deep inelastic scattering at NLO in the dipole picture [PDF]

Journal of High Energy Physics
We compute the transverse and longitudinal diffractive structure functions to full next-to-leading order accuracy in the dipole picture of deep inelastic scattering. Our calculation uses the standard light-cone perturbation theory method for the partonic
